problem #2

The automobile was stopped at a intersection and the pavement was wet from a light rain. I applied normal pressure to the accelerator and felt the car move forward as expected. Then the problem occurs, I felt the tires slip due to a lost of traction with the wet pavement. At that point the anti-skid/traction control engaged and stopped all power to the wheels. This left me part way into the intersection and no power to the wheels. Pressing the accelerator even to the floor resulted in no change, no motor or engine power. This has occurred three time in similar conditions, with mixed results. Twice the problem could of lead to an major accident. In summary this problem disable the drive train in a unpredictable manner that takes the driver out of the process.

Repeated braking at slow speeds resulted in both ABS and brake on signals, owner's manual says stop driving and contact dealer immediately. Drove slowly to dealer who ran diagnostics.($98)told to replace computer ($2000) not in stock. Told ok to drive until replacement. Adjusted something. Warning lights operated as expected. Situation recurred twice. Owner's manual indicated knowledge of possible failure. Also "parking brake abnormal status has appeared twice. No explanation in manual
